Description
Technical field
This utility model relates to a kind of blood-taking device, is specifically related to a kind of vacuum blood sampler for the blood sampling of rat jugular vein.
Background technology
The rat blood sampling is technology basic, the most the most frequently used in the scientific research, rat blood-sampling method commonly used comprises that broken end gets blood, abdominal aortic blood, cuts and get blood, heart puncturing extracting blood and taking blood from jugular vein after tail is got blood, eye socket, but most of blood extracting method affects experiment process and result because blood sampling volume not maybe can not repeat blood sampling.Simultaneously, in the blood sampling experimentation, most operator is transferred in the test tube after all using disposable syringe to adopt venous blood, and the moisture in the serum because affected by temperature and dry air to have evaporation in various degree, also is unfavorable for storing and mobile in uncovered test tube simultaneously.A lot of abecedarians also often cause that because of misoperation experimental data is inaccurate, such as direct injecting tube after the blood sampling of neck arteries and veins, and release fast, erythrocyte can be because being subjected to external force and high-speed impact test tube wall to cause haemolysis like this, or because syringe needle is not tight to connecting, air enters the generation foam during blood drawing, and haemolysis also easily occurs.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency on the prior art, thereby a kind of vacuum blood sampler for the blood sampling of rat jugular vein is provided, and its structure is reasonable, simple to operate, easy to use, easily is applied to animal blood taking in the laboratory.
The technical solution of the utility model is: a kind of vacuum blood sampler for the blood sampling of rat jugular vein, comprise blood taking needle, needle holder, vacuum tube, pipe close and safe head cap, described safe head cap is fastened on the pipe close outside and is fixed in the body port of vacuum tube, described pipe close is comprised of core plug and hermetically sealed case, described core plug is the M type, and core plug and hermetically sealed case are structure as a whole; Described vacuum pipe range is 8～10cm, and true footpath is 0.8～1.2cm.
Blood taking needle of the present utility model is fixedly connected with the bidirectional blood taking needle head, and the bidirectional blood taking needle afterbody is threaded with needle holder, and removably connects by needle holder and vacuum tube.
Described blood taking needle is straight blood taking needle or butterfly blood taking needle.
Another preferred version of the present utility model is: blood taking needle is the butterfly blood taking needle, and joint and the bidirectional blood taking needle head of butterfly blood taking needle afterbody removably connect, and bidirectional blood taking needle afterbody and vacuum tube removably connect.
This utility model compared with prior art has following effect: 1. vacuum tube of the present utility model has effectively prevented the problem of easily polluting after the blood sampling, evaporating, and has avoided experimental data therefore to cause inaccurate.2. this utility model utmost point is applicable to the abecedarian and carries out rat blood sampling, and the extraction action that operator can be follow-up after syringe needle is thrust vein has reduced the error probability in the operating process.3. product of the present utility model is used for that the jugular vein blood sampling is effective, wound is little, success rate is high, blood sampling volume is large, can repeatedly takes a blood sample.4. this utility model is simple in structure, and is easy to use, quick, manufactures easily, and cost is low, is convenient to promote the use of in the laboratory.

Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the decomposing schematic representation of this utility model specific embodiment one.
Fig. 3 is the structural representation of this utility model vacuum tube.
Fig. 4 is the structural representation of this utility model specific embodiment two.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1 ~ 3 explanation present embodiments, present embodiment is used for the vacuum blood sampler of rat jugular vein blood sampling, comprise blood taking needle, needle holder 6, vacuum tube 4, pipe close and safe head cap, safe head cap 3 is fastened on the pipe close outside and is fixed in the body port of vacuum tube 4, described pipe close is comprised of core plug 1 and hermetically sealed case 2, described core plug 1 is the M type, and core plug and hermetically sealed case are structure as a whole; Described vacuum pipe range is 8～10cm, and true footpath is 0.8～1.2cm.
In the present embodiment, blood taking needle is fixedly connected with the head 13 of bidirectional blood taking needle 12, and the afterbody 14 of bidirectional blood taking needle is threaded with needle holder 6, and removably connects by needle holder 6 and vacuum tube 4.
In the present embodiment, described blood taking needle is straight blood taking needle 7.
The specific embodiment two: present embodiment is described in conjunction with Fig. 4, the difference of present embodiment and the specific embodiment one is that blood taking needle 7 is butterfly blood taking needle 10, joint 11 and the bidirectional blood taking needle head 13 of butterfly blood taking needle afterbody removably connect, and bidirectional blood taking needle afterbody 14 removably connects with vacuum tube 4.During blood sampling, Handheld Division 9 inserting needles of the hand-held butterfly hemostix of experimenter.Other connected mode is identical with the specific embodiment one.
In the present embodiment, the additive 5 that experiment needs can be set in the bottom of vacuum tube 4.
Operation principle:
Extract pin medicated cap 8, with rat anterior pectorial region blood sampling site skin degerming, in the front median line approximately the 4th rib level thrust skin with the blood collection needles along continuous straight runs first, again to the jugular vein position along subcutaneous inserting needle, when syringe needle arrives the jugular vein position, angled 30 °～40 ° of blood collection needles and chest surface thrust to jugular vein, this moment blood collection needles and jugular vein to move towards direction consistent, the degree of depth of thrusting is 5 mm approximately, utilize the interior negative pressure of vacuum tube that blood is flowed in the vacuum tube automatically, when treating that blood is enough, extract blood taking needle, use the dry cotton ball pressing haemostatic, send control laboratory with vacuum tube.
